Have You Ever Wondered, "How Does a Segway Work"?The Segway personal transporter is a sophisticated piece of equipment that is much more complex than may first meet the eye. It takes a lot of technology and advanced engineering to make the Segway operate as it does on 2 wheels. Don't think that the Segway is anything like those cheap Chinese made stand up clones that you can get for $1000's less. There's no comparison. The Segway personal transporter is an amazing engineering marvel. It becomes more apparent at how truly remarkable this machine is when you understand a little more of how it works.
At the heart of the answer to the question "How does a Segway work?" is an advanced microprocessor control system. This microprocessor "brain" of the Segway takes information from 5 gyroscopic sensors which tells the onboard computer how much the Segway is leaning. The more the machine leans, the more that the motors turn the wheels in the direction needed to keep the Segway upright. When the operator leans to the side, the Segway adjusts motor speed and direction of each wheel to make a safe and controlled turn. This whole self balancing system is what is so remarkable about this machine.
Without these sophisticated controls, then it would be very difficult for a driver to master balancing on such a 2 wheeled transporter. In fact, without the sophisticated self balancing system, a 2 wheel scooter like this could probably only be ridden by highly trained person. It would be kind of like riding on a unicycle. It's not just something that anyone can just jump on and start riding immediately. Thankfully, that is not the case with the Segway's sophisticated control system. It is designed to be very user friendly with safety as a top priority. In fact, the Segway is designed with redundancy in all key areas to try to ensure the utmost in safety. For instance, only 3 gyroscopic sensors would be necessary to control such a machine, but the Segway incorporates 5 gyro sensors for extra redundancy and safety. In addition, motors have double windings so that if one set of windings fail, then the redundant windings help keep the motors running. Furthermore, the lithium ion battery packs are configured so that if some of the cells fail, then there should still be additional battery power available to keep the motors running. All this redundancy is intended to help make the Segway safer for the user. In a simplified summary statement, the answer to the question of how does a Segway work is as follows: the computerized brain takes input from sensors, which in turn determines how much power to send to each motor, so that the Segway remains upright while going in the direction (and at the speed) that the operator determines. Very simple to write, but no simple engineering feat to design and build such a machine. Segway has succeeded in doing this!
